Abstract
A display device includes a display area including a first light-emitting area and a second light-emitting area; a peripheral area adjacent to the display area; pixels which emit incident light; an encapsulation layer covering the pixels; a first color-converting pattern corresponding to the first light-emitting area and having a refractivity; a transmission pattern corresponding to the second light-emitting area and through which the incident light is transmitted; a low refractivity layer is in the display area and facing the encapsulation layer with each of the first color-converting pattern and the transmission pattern therebetween, the low refractivity layer including: a resin and a hollow particle which define a refractivity lower than the refractivity of the first color-converting pattern; and a first dam structure in the peripheral area and spaced apart from the display area, the first dam structure and the transmission pattern being portions of a same material layer.
